Apple first announced iOS7, its latest (and largest) iteration to its mobile operating system at its developer conference, WWDC, in June. Today, in its keynote address at its Apple Event 2013, still in progress, it said that iOS7 would be available for free to the public starting September 18. iOS 7 will be accessible to people who use the iPhone 4, iPad 2+, and iPad mini as well as the fifth generation iPod Touch.
The new operating system will introduce a wide array of features and the best round-ups can be found here, here and on Apple’s own website, here. We also wrote about the new signal indicators here.
